This is Bob's.  (apparently the Supercom author!)

I think the NOS9 xmode is the one matching SACIA.  This is part of the
eliminator driver software package, which is somewhere on RTSI
(elim.lzh).  It describes SACIA, DACIA, and the new xmode in detail.

I don't know about NOS9, but regular old OS-9LII with SACIA couldn't do
zmodem at more than 4800 without losing characters.  IIRC this is
because zmodem has to read one character at a time, and above 4800
this just takes too long.  I don't know if this is a fundamental flaw
in the design of zmodem, or just because OS-9 zmodem is a port of UN*X
zmodem. 

IIRC I could download at 9600 with xmodem or ymodem.
